Workflow Systems

A single calculator answers one question. Most real decisions need several, in order, with the answer from one feeding the next: what a financed machine costs per month, what that does to the volume you must sell, what price makes that volume reachable.

Each system below is that sequence written down. Open one and the calculators appear in order at the top of the page, already filled in with a worked example. Change a figure and it carries into the later steps that use the same field, and every result collects into a summary you can copy or print. The written walkthrough sits underneath if you want the reasoning rather than just the arithmetic.

Construction covers estimating and job costing: take-offs through burdened labor to a quoted price, then variance while the job is still running. Finance covers break-even, overhead rates, equipment finance and the thirteen-week cash forecast that catches the gap between profitable and solvent. Freelance covers billable capacity, rate setting and what survives self-employment tax. QR covers running a print campaign end to end and measuring it against margin.

Nothing here needs an account, and the calculators run in your browser, so the figures you type are never uploaded. Several systems also include a spreadsheet if you would rather keep the numbers yourself.
